[0006] In a first aspect, an embodiment of the present application provides a housing, the housing comprising a base, an air suction duct, an air outlet duct, and a dust collection duct;

[0007] The base has a mounting cavity for placing the dust box;

[0008] The air suction duct is connected to the air outlet duct, the air outlet duct and the dust collection duct are located on the same side of the installation cavity, the air suction duct and the dust collection duct are both connected to the dust box, and the air outlet duct and the dust collection duct are both used to communicate with the external environment.

[0009] The shell provided in the embodiment of the present application arranges the air outlet duct and the dust collection duct on the same side of the installation cavity. Both the air outlet duct and the dust collection duct are used for air discharge, and are both used to connect to the external environment. In the prior art, the aforementioned two channels are arranged on the left and right sides of the cleaning equipment, which may lead to problems such as the pipeline being too long and too many bends. By arranging the air outlet duct and the dust collection duct on the same side of the cleaning equipment, the airflow channel layout and the airflow transmission path inside the cleaning equipment can be optimized, making the air path structure more compact, which is conducive to reducing the volume of the cleaning equipment and meeting the user's demand for miniaturization of the product.

[0010] In a second aspect, an embodiment of the present application further provides a cleaning device, including a shell and a dust box, wherein the shell includes a base, an air suction duct, an air outlet duct, and a dust collection duct;

[0011] The dust box is installed on the base;

[0012] The air suction duct is connected with the air outlet duct, the air outlet duct and the dust collecting duct are both located on the same side of the dust box, the air suction duct and the dust collecting duct are both connected with the dust box, and the air outlet duct and the dust collecting duct are both used to communicate with the external environment.

[0013] The cleaning device provided in the embodiment of the present application has the air outlet duct and the dust collection duct arranged on the same side of the installation cavity. The air outlet duct and the dust collection duct are both used for air discharge, and are both used to connect to the external environment. In the prior art, the aforementioned two channels are arranged on the left and right sides of the cleaning device, which may lead to problems such as the pipeline being too long and too many bends. By arranging the air outlet duct and the dust collection duct on the same side of the cleaning device, the airflow channel layout and the airflow transmission path inside the cleaning device can be optimized, making the air path structure more compact, which is conducive to reducing the volume of the cleaning device and meeting the user's demand for miniaturization of the product.

[0014] In the above-mentioned cleaning device, optionally, the output end of the air outlet duct and the output end of the dust collecting duct are arranged adjacent to each other, and both are located on the same side of the dust box.

[0015] Through the above arrangement, the cleaning device can be provided with other structures in a limited space, thereby improving the space utilization of the cleaning device, which is conducive to realizing the miniaturized design of the cleaning device and meeting the needs of users.

[0016] In the above-mentioned cleaning device, optionally, the input end of the air outlet duct and the input end of the dust collecting duct are arranged at intervals and are both located on the same side of the dust box.

[0017] Through the above arrangement, the interval can be used to place the suction fan, which can improve space utilization, help reduce the size of the cleaning equipment, and meet users' needs for miniaturization of products.

[0018] In the above-mentioned cleaning device, optionally, the shell further includes a dust collecting cover plate, and the dust collecting cover plate and a portion of the base are surrounded to form the dust collecting air duct.

[0019] Through the above arrangement, the cleaning equipment only needs one dust collecting cover plate to form a dust collecting air duct. Compared with the solution of two cover plates in the prior art, the number of structures required for the dust collecting air duct can be reduced, thereby reducing costs. In addition, in the prior art, the two cover plates first need to be connected to form an air duct, and then the connected structure is installed on the base, which requires multiple positioning and multiple connections. The dust collecting air duct provided in the embodiment of the present application only needs one positioning and one connection to form a dust collecting air duct, which can reduce the assembly process and thus improve the assembly efficiency.

[0020] In the above-mentioned cleaning device, optionally, the base is made of the same material as the dust collecting cover.

[0021] By using the same material, the consistency of the processing technology of the base and the dust collecting cover can be ensured, which helps to improve production efficiency and thus reduce production costs.

[0022] Secondly, by using the same material, the base and the dust collecting cover can have the same physical properties, such as strength, rigidity and impact resistance, which helps to improve the overall structural stability and durability of the cleaning equipment and ensure that the cleaning equipment can operate stably.

[0023] In addition, the same thermal expansion coefficient of the same material can avoid inconsistent dimensional changes between the base and the dust collecting cover due to temperature changes, thereby reducing assembly problems caused by thermal expansion or contraction and improving the reliability and service life of the cleaning equipment.

[0024] In the above cleaning device, optionally, the dust box has a accommodating cavity and a dust inlet, an air inlet and a dust outlet connected to the accommodating cavity, and the dust inlet is used for allowing dirt to enter the dust box for storage;

[0025] The input end of the air inlet duct is connected to the air inlet port, and the input end of the dust collecting duct is connected to the dust outlet port.

[0026] Through the above arrangement, dirt can enter the dust box through the dust inlet, the airflow in the dust box can be moved out through the air inlet, and the dirt in the dust box can be moved out through the dust outlet, thereby realizing the dirt collection and dirt transfer out of the dust box.

[0027] In the above-mentioned cleaning device, optionally, in the height direction of the cleaning device, the air inlet is higher than the dust outlet and the dust inlet;

[0028] and / or,

[0029] The air inlet and the dust outlet are arranged on the same surface of the dust box, and the dust inlet and the dust outlet are arranged on different surfaces of the dust box.

[0030] Through the above arrangement, the higher air inlet position can make the air flow smoothly downward inside the dust box, which can reduce the resistance and energy loss of the air flow during the transmission process and improve the transmission efficiency of the air flow.

[0031] In the above cleaning device, optionally, it further includes a suction fan, and the suction fan is located between the suction duct and the outlet duct;

[0032] The length of the air outlet duct is greater than the length of the air suction duct.

[0033] Through the above-mentioned arrangement, the longer air outlet duct can reduce the air flow velocity and reduce the noise generated when the air flow is discharged, which can reduce noise pollution and help improve the comfort of use of the cleaning equipment.

[0036] The cleaning system provided in the embodiment of the present application can optimize the airflow channel layout and airflow transmission path inside the cleaning device by arranging the air outlet duct and the dust collection duct on the same side of the cleaning device, so that the air path structure is more compact, which is beneficial to reducing the volume of the cleaning device and meeting the user's demand for miniaturization of the product.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] In a first aspect, an embodiment of the present application provides a cleaning system (not shown in the figure), including a base station (not shown in the figure) and a cleaning device 10.

[0061] It is understood that after the cleaning device 10 completes cleaning of the cleaning surface, it can be placed on the base station for placement, charging or self-cleaning. The base station is provided with a placement position for the cleaning device 10, so that the cleaning device 10 can be positioned and placed. The base station is provided with a charging interface, so that the cleaning device 10 can be charged.

[0062] It should be noted that the base station generally needs to be placed on the ground to support the operation of the cleaning device 10 .

[0063] It is understandable that the cleaning device 10 can be different types of devices. For example, the cleaning device 10 can be a sweeping robot, a sweeping and mopping robot, or a vacuum cleaner, etc. Different types of cleaning devices 10 all have corresponding base stations.

[0064] The following description will be made by taking the cleaning device 10 as a sweeping robot as an example.

[0065] Reference Figure 1In a second aspect, an embodiment of the present application further provides a cleaning device 10, including a shell 100 and a dust box 200, the shell 100 includes a base 110, the dust box 200 is installed on the base 110, and the dust box 200 is used to collect dirt.

[0066] Reference Figure 2 In some embodiments, the base 110 has an installation cavity 111 for placing the dust box 200, and the dust box 200 can be located in the installation cavity 111. It can be understood that the base 110 also has a dirt suction port connected to the installation cavity 111, and the dirt suction port is used to suck dirt so that the dirt enters the dust box 200 to complete the cleaning work. That is, the dirt enters the dust box 200 located in the installation cavity 111 through the dirt suction port.

[0067] Reference Figure 2 Specifically, the shell 100 also includes an air suction duct 120, an air outlet duct 130 and a dust collection duct 140. The air suction duct 120 and the dust collection duct 140 are both connected to the dust box 200, the air suction duct 120 is connected to the air outlet duct 130, and the air outlet duct 130 and the dust collection duct 140 are both used to communicate with the external environment.

[0068] It is understandable that the suction airflow flows through the suction duct 120, and under the action of the suction airflow, negative pressure is formed inside the dust box 200, so that dirt can enter the dust box 200 through the dirt suction port, thereby completing the cleaning work. Figure 1 and Figure 3 , path a is the path of the suction airflow, path b is the path of dirt entering the base station from the dust box 200, and path c is the path of dirt entering the dust box 200 from the surface to be cleaned. It can be understood that path a and path c occur simultaneously, that is, path c absorbs dirt through the airflow generated by path a. Path b occurs independently.

[0069] The base station has a collection channel corresponding to the dust collection duct 140; when the cleaning device 10 is docked with the base station, the input end of the collection channel is connected to the output end of the dust collection duct 140. Correspondingly, a dust bag connected to the collection channel is also provided on the base station, and the base station can collect the dirt collected by the cleaning device 10 after cleaning into the dust bag through the collection channel.

[0070] It is understandable that the dust bag usually has a large capacity and can collect dirt collected by the cleaning device 10 for multiple times. When the dirt collected by the dust bag reaches the maximum capacity, the cleaning system can prompt the user to clean the dust bag. The way to prompt the user includes but is not limited to a prompt sound, a prompt light, etc.

[0071] It should be noted that, in order to complete the collection of dirt, a collection fan is also provided in the base station, and the collection fan is connected to the collection channel (essentially the dust collection duct in the base station), and the collection fan can provide suction. When the base station is docked with the cleaning device 10, the input end of the collection channel is connected to the output end of the dust collection duct 140, and the output end of the collection channel is connected to the dust bag. The collection fan works and provides suction and absorbs dirt, so that the dirt can be separated from the dust collection duct 140 of the cleaning device 10 and enter the collection channel, and enter the dust bag through the collection channel to complete the collection of dirt.

[0072] It should be noted that in order to prevent the dirt in the dust box 200 from being discharged from the dust box 200 along the suction duct 120, a filtering structure can also be provided in the dust box 200. The filtering structure can filter the dirt so that the dirt stays in the dust box 200 and will not affect the suction fan 300.

[0073] Reference Figure 2 In some embodiments, the cleaning device 10 further includes a suction fan 300, which is located between the suction duct 120 and the outlet duct 130, that is, the suction fan 300 is connected to the left side of the suction duct 120 and the right side of the outlet duct 130 respectively, and the suction fan 300 can provide the aforementioned suction airflow to generate negative pressure inside the dust box 200, thereby sucking dirt through the suction port. Figure 2-Figure 3 The air flows through the air outlet duct 130 to the outside of the cleaning device 10. Figure 1-Figure 3 The a path in .

[0074] According to the above content, the dust collecting duct 140 is used to transfer the dirt from the cleaning device 10 to the base station. That is, the input end of the dust collecting duct 140 is connected to the dust box 200. When the cleaning device 10 is docked with the base station, the dust collecting fan works and provides suction to absorb the dirt. Figure 2-Figure 3 The c path in the figure allows dirt to enter the dust collecting duct 140 from the dust box 200. Figure 1-Figure 3 The dust passes through the path b in the dust collecting passage 140, and then enters the collection passage, and enters the dust bag through the collection passage to complete the collection of the dirt.

[0075] It is understandable that the suction fan 300 can be installed on the base 110 through the mounting frame 400. Both ends of the mounting frame 400 can be connected to the air inlet channel and the air outlet channel respectively.

[0076] In some embodiments, the air outlet duct 130 and the dust collection duct 140 are both located on the same side of the dust box 200. The aforementioned same side includes but is not limited to the left side, right side, front side or rear side of the dust box 200. Figure 1-Figure 3 The air outlet duct 130 and the dust collecting duct 140 are both located on the left side of the dust box 200 .

[0077] It is understandable that the air outlet duct 130 and the dust collection duct 140 are both used for air discharge and are both used to connect to the external environment. The layout of the two channels in the prior art, which are respectively arranged on the left and right sides of the cleaning device 10, may lead to problems such as the pipeline being too long and too many bends. By arranging the air outlet duct 130 and the dust collection duct 140 on the same side of the cleaning device 10, the air flow channel layout and air flow transmission path inside the cleaning device 10 can be optimized, making the air path structure more compact, which is conducive to reducing the volume of the cleaning device 10 and meeting the user's demand for miniaturization of the product.

[0078] Reference Figure 2 As an optional implementation, the output end of the air outlet duct 130 is arranged adjacent to the output end of the dust collecting duct 140 .

[0079] See attached Figure 2 It can be seen that the output end of the air outlet duct 130 and the output end of the dust collecting duct 140 are both located on the left side of the cleaning device 10, and the distance between the output end of the air outlet duct 130 and the output end of the dust collecting duct 140 is small, forming an adjacent arrangement.

[0080] As can be seen from the accompanying drawings, the output end of the air outlet duct 130 and the output end of the dust collection duct 140 are both located on the left side of the dust box 200 .

[0081] Through the above arrangement, the cleaning device 10 can be provided with other structures in a limited space, thereby improving the space utilization of the cleaning device 10, which is conducive to realizing the miniaturized design of the cleaning device 10 and meeting the needs of users.

[0082] Reference Figure 2 As an optional implementation, the input end of the air outlet duct 130 and the input end of the dust collecting duct 140 are spaced apart and are both located on the same side of the dust box 200 .

[0083] Referring to the accompanying drawings, it can be seen that the input end of the air outlet duct 130 and the input end of the dust collecting duct 140 are both located on the left side of the dust box 200, and the distance between the input end of the air outlet duct 130 and the input end of the dust collecting duct 140 is relatively large, forming an interval arrangement. In addition, according to the accompanying drawings, it can be seen that the output end of the air outlet duct 130 and the output end of the dust collecting duct 140 are both located on the left side of the dust box 200.

[0084] It is understandable that the above-mentioned interval can be used to place the suction fan 300, which can improve the space utilization rate, help to reduce the volume of the cleaning device 10, and meet the user's demand for miniaturization of the product.

[0085] Reference Figure 2As an optional embodiment, the length of the air outlet duct 130 is greater than the length of the air suction duct 120. That is, the air outlet duct 130 occupies a longer path, and the air suction duct 120 is relatively short.

[0086] It is understandable that a longer air outlet duct 130 can reduce the air flow velocity and reduce the noise generated when the air flow is discharged, which can reduce noise pollution and help improve the comfort of use of the cleaning device 10.

[0087] It should be noted that in the embodiment of the present application, the distance between the suction fan 300 and the dust box 200 is relatively short, that is, the suction end of the suction fan 300 is directly connected to the dust box 200. The relatively short distance can form the aforementioned suction duct 120, resulting in a relatively short length of the suction duct 120.

[0088] It should be noted that in the attached Figure 1 , Attachment Figure 2 And attached Figure 3 In the figure, on the base 110, except for the dust box 200, the dust collecting cover 500, the suction fan 300 and the mounting frame 400 shown, the structures of other areas are not shown.

[0089] Reference Figure 4 , Figure 5 As an optional embodiment, the housing 100 further includes a dust collecting cover 500, and the dust collecting cover 500 and a part of the base 110 are arranged to form a dust collecting air duct 140. Specifically, the dust collecting cover 500 can be located above the base 110 in the height direction H, and the dust collecting air duct 140 is formed between the dust collecting cover 500 and the base 110.

[0090] It should be noted that the height direction H indicated in the embodiment of the present application is only used for the Figure 4 -Attached Figure 6 The relative positional relationship between different structures is not equivalent to the actual application. For example, in actual application, the dust collecting cover 500 is located below the base 110 in the direction of gravity. The height direction H will not be described below.

[0091] Specifically, the base 110 may include a bottom plate 113, a first plate 114, and a second plate 115. The first plate 114 and the second plate 115 are both disposed on the bottom plate 113, and the first plate 114 and the second plate 115 may be disposed at an interval. Figure 4 , Attachment Figure 5 It can be seen that the first plate 114 and the second plate 115 are respectively arranged perpendicular to the bottom plate 113. The first plate 114, the second plate 115 and a portion of the bottom plate 113 located between the first plate 114 and the second plate 115 surround and form the lower half of the dust collecting air duct 140.

[0092] It is understandable that in order to improve the structural strength of the dust collecting duct 140, the first plate 114, the second plate 115 and the bottom plate 113 can be an integral part, that is, the bottom plate 113, the first plate 114 and the second plate 115 can be integrally formed, such as by casting.

[0093] The dust collecting cover 500 includes a cover body 510 and two side plates 520 connected to both sides of the cover body 510 . The cover body 510 and the two side plates 520 can surround and form the upper half of the dust collecting air duct 140 .

[0094] It can be understood that when the two side plates 520 of the dust collecting cover plate 500 are respectively connected to the first plate 114 and the second plate 115 , a dust collecting air duct 140 can be formed between the dust collecting cover plate 500 and the base 110 .

[0095] Through the above arrangement, the cleaning device 10 only needs one dust collecting cover plate 500 to form the dust collecting air duct 140. Compared with the solution of two cover plates in the prior art, the number of structures required for the dust collecting air duct 140 can be reduced, thereby reducing costs. In addition, in the prior art, the two cover plates first need to be connected to form the air duct, and then the connected structure is installed on the base 110, which requires multiple positioning and multiple connections. The dust collecting air duct 140 provided in the embodiment of the present application only needs one positioning and one connection to form the dust collecting air duct 140, which can reduce the assembly process and thus improve the assembly efficiency.

[0096] As an optional implementation, the base 110 is made of the same material as the dust collecting cover 500 .

[0097] Specifically, the base 110 may be made of plastic. For example, the base 110 may be made of one or more materials including, but not limited to, ABS (Acrylonitrile-butdiene-styrene), PC (Polycarbonate), PP (Polypropylene), PVC (Polyvinyl Chloride), PS (Polystyrene) and PA (Polyamide).

[0098] The dust collecting cover 500 is made of the same material as the base 110, and will not be described in detail herein. The embodiment of the present application does not limit the specific materials used to make the base 110 and the dust collecting cover 500, nor is it limited to the above examples.

[0099] The following description will be made by taking the base 110 and the dust collecting cover 500 as an example in which they are made of ABS material.

[0100] By using the same material, the consistency of the processing technology of the base 110 and the dust collecting cover plate 500 can be ensured, which helps to improve production efficiency and thus reduce production costs.

[0101] Secondly, by using the same material, the base 110 and the dust collecting cover plate 500 can have the same physical properties, such as strength, rigidity and impact resistance. In this way, it helps to improve the overall structural stability and durability of the cleaning device 10 and ensure that the cleaning device 10 can operate stably.

[0102] In addition, the same material has a consistent thermal expansion coefficient, which can avoid inconsistent dimensional changes between the base 110 and the dust collecting cover 500 due to temperature changes, thereby reducing assembly problems caused by thermal expansion or contraction, and improving the reliability and service life of the cleaning device 10.

[0103] Reference Figure 6 As an optional embodiment, the dust box 200 has a receiving chamber 201. The receiving chamber 201 is used to store the dirt collected during the cleaning process. The dust box 200 also has a dust inlet 202, an air inlet 203 and a dust outlet 204 connected to the receiving chamber 201. The dust inlet 202 is used for the dirt to enter the dust box 200 for storage.

[0104] It is understandable that the dust inlet 202 allows dirt to smoothly enter the accommodating cavity 201 of the dust box 200, which can improve the collection efficiency of dirt. The input end of the air inlet duct is connected to the air inlet 203, and the input end of the dust collection duct 140 is connected to the dust outlet 204, that is, the air inlet duct can be connected to the dust box 200 through the air inlet 203, and the dust collection duct 140 can be connected to the dust box 200 through the dust outlet 204.

[0105] It should be noted that the position and shape of the dust inlet 202 can be selected according to actual needs to adapt to different cleaning scenes and types of dirt, further improving the adaptability and cleaning effect of the cleaning device 10, and the embodiment of the present application does not limit this. The position and shape of the dust outlet 204 and the air inlet 203 can refer to the description of the dust inlet 202, and will not be repeated here.

[0106] Through the above arrangement, dirt can enter the dust box 200 through the dust inlet 202, the airflow in the dust box 200 can be moved out through the air inlet 203, and the dirt in the dust box 200 can be moved out through the dust outlet 204, thereby realizing the dirt collection and dirt transfer out of the dust box 200.

[0107] Reference Figure 6 As an optional implementation, the dust inlet 202 and the dust outlet 204 are opened on different surfaces of the dust box 200, so that it can be ensured that the dirt can smoothly enter the dust box 200 and be effectively collected.

[0108] In the embodiments of this application, refer to Figure 2 , Figure 3 as well as Figure 6 The base 110 also has a dirt inlet 112, which is used to allow dirt to enter the installation cavity 111 so as to enter the dust box 200 to complete the cleaning operation. It can be understood that the dust inlet 202 corresponds to the dirt inlet 112, that is, dirt can enter the dust box 200 through the dirt inlet 112 and the dust inlet 202.

[0109] Reference Figure 6 Furthermore, the air inlet 203 and the dust outlet 204 are opened on the same side of the dust box 200, that is, on the left end face of the dust box 200. In this way, the flow path of the airflow inside the dust box 200 can be simplified, the resistance and energy loss of the airflow during the transmission process can be reduced, and the transmission efficiency of the airflow can be improved.

[0110] Reference Figure 6 As an optional embodiment, in the height direction H of the cleaning device 10, the air inlet 203 is higher than the dust outlet 204 and the dust inlet 202;

[0111] It is understandable that, under the action of the aforementioned suction fan 300, a negative pressure can be formed inside the dust box 200. Under the action of the negative pressure, the airflow can drive dirt into the dust box 200 through the dirt inlet 112 and the dust inlet 202.

[0112] It should be noted that, according to the above content, a filter 210 is provided in the dust box 200. In some embodiments, the filter 210 can directly cover the input end of the air suction duct 120, that is, directly cover the air inlet 203. In this way, the filter 200 can block dirt and only allow air to flow out through the air inlet 203, so that the dirt is kept in the dust box 200;

[0113] In some other embodiments, the filter element 210 is larger in size and can cover a portion of the accommodating cavity 201 of the dust box 200 , that is, it is located between the air inlet 203 and the dust inlet 202 in the height direction H to keep the dirt in the dust box 200 .

[0114] As an optional implementation, a first sealing plate 220 and a second sealing plate 230 are respectively disposed at the positions of the dust inlet 202 and the dust outlet 204 , and the first sealing plate 220 and the second sealing plate 230 are both rotatably disposed in the dust box 200 .

[0115] In the first case, that is, when the cleaning device 10 is docked with the base station, the collection channel can release suction airflow to the dust collection air duct 140. Under the action of negative pressure, the second sealing plate 230 can rotate to open the dust outlet 204, so that the dirt inside the dust box 200 can enter the dust bag through the dust collection air duct 140 and the collection channel. Figure 1-Figure 3 The b path in .

[0116] In the second case, when the cleaning device 10 is in the cleaning operation, the suction fan 300 can provide suction airflow, so that the air pressure of the suction duct 120 is low, and the suction duct 120 is connected with the air inlet 203, so that the dust box 200 is in a negative pressure state. Under the action of negative pressure, the first sealing plate 220 can rotate and open the dust inlet 202 to facilitate the suction of dirt. Then, the dirt enters the dust box 200 through the dirt suction port 112 and the dust inlet 202. Figure 2-Figure 3 At the same time, the airflow released by the suction fan 300 flows from the air outlet duct 130 to the outside of the cleaning device 10. Figure 1-Figure 2 Path a in the figure, thereby completing the cleaning operation of the cleaning device 10.
